Filed Jan. 18, 1961, Ser. No. 83,455 4 Claims. (Cl. 282-49) This invention relates to the art of manifolding in which continuous strips of stationery are interleaved 'with continuous long strips of carbon paper which may be discarded after making several copies, and more particularly to a pack of transfer material for such use.

The advantages of a fiat transfer material pack for use in manifolding are well recognized in the field. To be commercially successful a transfer material pack must be competitively priced, and easy to handle and use. Ease in progressively removing new transfer material from the pack as the old is discarded after making several copies is of prime importance along with a pack design which may be economically manufactured so as to be competitive in the market. In addition to satisfying manufacturing economies the design must be of such a nature that the pack is adequately durable and rugged for its intended function.

It is a primary object of this invention to provide a new and improved pack of transfer material for use in manifolding.

An important object of the invention is to provide a competitive pack of transfer material which is both durable and rugged, and easy to use.

Another object of the invention is to provide a fiat pack of staggered, Zig-zag folded transfer material which may be simply and easily progressively withdrawn from the pack.

Other objects, features and advantages of the present invention will be apparent from the following description of a preferred embodiment illustrated in the accompanying drawings, in which:

FIGURE 1 is a fragmentary perspective view of a manifolding flat pack of transfer material made in accordance with the present invention;

FIGURE 2 is a perspective view, to a reduced scale, of a zig-zag folded strip of transfer material for assembly into a pack of transfer material; and

FIGURE 3 is a broken sectional view taken generally along the line 33 of FIGURE 1, and to an exaggerated vertical scale to more clearly illustrate the construction.

Continuous form stationery is used in a great many business oflices, often with car-bonpaper which is held between superimposed strips of stationery to make a manifolding assembly. The manifolding assembly may thus pass around a platen of a writing, or billing, or similar machine to receive the desired imprinting. The carbon paper is generally used a number of times after which it may be removed from the assembly and discarded as an additional length of carbon paper is led forwardly to provide fresh, clean carbon paper in the manifolding assembly.

The present invention is, in brief, directed to a flat pack of transfer material such as carbon paper folded in such a manner that it may be attached to a flap of the carrier by adhesive tapes and progressively withdrawn from the carrier with the adhesive portion of the released tape immediately adjacent the flap for adhering to the flap.

Referring to the drawings, in the illustrated embodiment a long strip of transfer material 10, such as carbon paper, is detachably secured to a base 11 in such a manner that the strip may be progressively withdrawn from the base by pulling a free end 12 of the strip outwardly from the base.

In the present embodiment the base 11 is in the form of one flap of a folder having a second or cover flap 13 hinged to the base flap 11 by a fold 14 and providing a carrier member 15, preferably of stiff paper, for the strip of transfer material 10.

In order to firmly secure the strip of transfer material 10 to the carrier 15, and to provide for easy withdrawal of the strip from the carrier during normal usage of the pack, the strip 10 is folded upon itself in zig-zag fashion with folds 16 offset from each other in the same direction at one end of the folded strip, thereby exposing a portion 17 of the strip in the form of a band adjacent each fold.

Securing of the folded strip of transfer material 10 to the carrier 15 in a rugged manner which permits the strip to be easily progressively withdrawn from the carrier during normal usage is provided by one or .more tapes, and in the illustrated embodiment by three tapes 18. A surface 19 of each tape 18 faces the exposed portions 17 of the strip .10 and the base flap 11 of the carrier member 15. This surface is preferably provided with a pressure sensitive adhesive coating which detachably secures the tapes 18 to the exposed portions 17 of the strip and to the base flap 11 with offset folds 16 positioned adjacent the connected ends of the base and cover flaps.

A leading portion 20 of the strip on the base flap 11 extends away from the carrier fold 14 between the offset folds 16 and the base flap 11 and provides the free end 12 of the strip which may be pulled for progressively withdrawing the layers of the strip of transfer material 10 from the pack. As each exposed portion 17 or band of the strip is released from the adhesive faces 19 of the tapes 13 the adhesively coated face 19 engages the base flap '11 more securely attaching each tape to the base flap and eliminating any possibility of the adhesively coated face 19 interfering with subsequent progressive withdrawal of the strip 10. Thus it is merely necessary in removing the strip of transfer material from the pack for the user to pull the free end 12 of the strip away from the pack without con cerning himself with disposal or handling of the tapes 18.

In the preferred embodiment illustrated in the drawings, the strip 10 has transfer material applied only to one side 21 thereof. The transfer material coated side 21 of the strip is concealed from the carrier flaps to protect the coating of transfer material, and the tapes 18 are adhesively secured to the opposite side 22 of the strip 10 which may be coated with tale in a WaX carrier so that the tapes 18 may be easily released from the strip 10 without marring the coating of transfer material. It should also be noted that as the strip 10 is withdrawn from the pack the tale and wax coated face 22 slides across the face of the base flap 11 and the transfer material coated side 21 rides against similar transfer material coated portions of the strip to further retard marring of the transfer material coating.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom for some modifications will be obvious to those skilled in the art.

I claim:

1. A pack of transfer material comprising: a base; a strip of transfer material zig-zag folded in an offset manner to provide exposed portions of the strip adjacent each fold, said strip being received on said base with said exposed portions facing outwardly of said base and a free end of the strip extending out of the pack between the folded strip and said base; and a tape secured to said base, said tape being detachably secured to said exposed portions and being exposed to said base upon removal of an exposed portion of the transfer strip from the tape.

2. A pack of transfer material comprising: a base; a strip of transfer material zig-zag folded with offset folds to provide exposed portions of the strip adjacent each fold, said strip being received on said base; a tape having an adhesive on one surface detachably secured by means of said adhesive to said exposed portions and to said base; and a leading portion of said strip extending between said base and the remainder of said Zig-zag folded strip, said leading portion having a free end for pulling said strip from said base and successive exposed portions out of adherence with said tape so as to expose the adhesive on the tape to contact with the base only.
